Be it known that I, WILLIAM SoRiMeEoUn, Jr., a citizen of the United States, residing at Portsmouth, in the-"county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Furnaces or Forges'of which the following is a specification. g

This lilrelltion' relates to furnaces orl forgesutilizing oilor gas as fuel, the' object simple, inexpensive and eiiicient furnace, adapted for various purposes and more particularly for the working of metals..

For a fulli unders anding of the inventu tion reference, is made to the accompanying drawing showing a preferred embodiment v Figure 1 is a longitudinal lvertical sec- Figa` 3; Fig. 2 is a transverse section on line 2 2 of Fig. 1; and Fig. 3 1s a plan View- The furnace illustrated is constructed of refractory brick. incasedby asbestos sheathing 3 or equivalent refractory material of low heat-conductivity, -covered by a ycasing` 1, usually 'oisheet or cast metal.. Angle bars 2 serve to strengthen the cornersand sides of the brickworl. and may also serre if the upper edges of thebrickwork are shown as protected by coping-plates 15.

4 isan orifice inthe forward vend ot" the furnace for. a suitable hydro-carbon or gas burner 4, the flame from which is directed into a combustion chamber 5. .This combustion chamber is shown as substantially horizontally disposed withintbe briclzwork, and commu'mcates directly withy a suppley mental c :ombfustim'1 chamber or heating chamber, which extends' upwardly to the top of' the v loriclr'work and wit'hin'or over which the article to be. heated is .placed. The combustion chamber V5 is' preferably provided; with a divergentthroat for the downwardly tofthe heating' chamber 6 and in order ,ltoavoid-. contracti'ouits cross sectional area the combustion chamber is v rommel.: on sones.

3. The combination in an apparatus of the class described, of a setting, a supplemental combustion chamber therein having its outlet at the surface of the setting, a combustion chamber having a. sloping upper surface and having an extended bottom forming the .bottom of the said supplement-al combustion chamber', avent from said supplemental combustion chamber,l a sla trap or cavity connected therewith, a horizontal flue connected to the trapv at its upper portion, a. transverse line connected therewith, and a U shaped flue connected to said transverse Hue and .adapted to partly surround said combustion chamber.
